$5 part could save our A**

Don't know if this has been posted before or not.


I am replacing this as soon as I head out the door after typing this. My normal temp is around 194 degrees based upon my H&S gauge and I haven't noticed any coolant loss but I also have only 46k miles on my truck


I hope once I put this on I do not have new issues pop up b/c the next weak link gives.

I plan on buying one on the way home today. I will then check to see if I have one of the newer caps already installed. If I do then I will hold on to the one just purchased, just in case.
Interesting video. great information. Any further research out there on this issue?

Great Info! Just looked at the cap on my 2008 6.4L, and it's one of the old type. Picking up a new one this afternoon.

As well as the cap I suggest a light sanding...very lightly where the cap goes before you put it on.

You want to ensure it is smooth and free of any coolant and rough edges.

Does not take much.

Checked mine last night , had the old cap, stopped and picked up the new cap yesterday and took it out for a test drive! New cap holds pressure no problem... The last cap wouldn't hold the pressure just like explained on the video ! I was able to boost all the way up to 45psi according to my livewire without issue ... I thought for sure my head gaskets were gone a few weeks ago ! But this simple $5 part saved me a TON of $$$$! I reccomend this cap to everyone !
